• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((((yang yi) OR (ying hua))) OR (yang hui)) ((yin yang) OR (ying yang)) di song shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((yang yi) or (ying hua))) or (yang hui)) ((yin yang) OR (ying yang)) di song shu ;*".
